2nd session of Core Synergistics.  Really tried to engage the core this time.  Maybe I’m just not strong enough in the rest of my muscle groups because there are a few of the exercises that I still don’t feel much of anything in the core.  Certainly the push-ups, plank, chatarangu(?) banana/superman, banana rolls, bow/boats all hit the core without really trying.  Some of the lunge stuff just doesn’t seem to work anything for me but the legs.  Still working up a sweat though.  I’ll take it.  Feels good and it’s P90X so I’ll keep pushing play and Bring It!
